Tommy D. Rossi 7fe09ea35e liveline: JetBrainsMono Nerd Font Mono for code blocks, fix diagram alignment
- Add @font-face for JetBrainsMono Nerd Font Mono (nerd-fonts v3.3.0) with
  proper box-drawing glyph support for seamless Unicode diagram rendering
- Update --ll-font-code to use NF Mono as primary, fallback to JetBrains Mono/SF Mono
- Fix liveline-prism.css: use var(--ll-font-code) instead of hardcoded SF Mono
- Remove unused Google Fonts JetBrains Mono link from root.tsx
- Fix diagram: keep Unicode box chars for seamless lines, use ASCII < > v for
  arrows (◄ ► ▼ render at inconsistent widths), recount all columns

/*
* Liveline page styles - recreating benji.org's editorial design system.
*
* Key design decisions from the original:
* - Inter variable font at weight 460 (between normal and medium)
* - Near-black text (#111) not pure black, with 40% opacity for secondary
* - Narrow 550px content column for optimal reading
* - Negative letter-spacing on headings for tight, refined feel
* - 7-layer box shadows for realistic depth
* - Display P3 accent colors (wider gamut than sRGB)
* - Staggered entrance animations with subtle translateY
* - Custom cubic-bezier easings with slight overshoot ("snappy", "swift")
* - Fading header gradient pseudo-element
* - Small font sizes (14px body) for editorial/compact aesthetic
*/
